Callista Media Group

Callista Media Group is a Los Angeles-based out-of-home advertising company specializing in mobile billboards and large-format urban displays. Its core product is moving billboard trucks, which the company can deploy in fleets of up to fourteen vehicles for a single campaign, driving branded creative through high-traffic streets and around targeted destinations. Alongside its trucks, Callista offers wallscape advertising in dense urban areas, giving brands access to oversized building-mounted displays that command attention at street level.

The company frames its approach as guerrilla out-of-home marketing focused on maximizing street-level brand exposure, describing its placements as "unskippable ads" that transform ordinary trucks into moving canvases within the urban landscape. To connect physical exposure with measurable outcomes, Callista integrates digital retargeting and A/B testing into its campaigns, allowing advertisers to follow up on real-world impressions with online messaging and to compare creative performance. The company markets competitive pricing, citing reduced CPMs relative to other channels, and promotes internally referenced lift metrics for brand recall and post-campaign digital engagement.

Its client examples span technology, beverage and entertainment categories, including work referenced for brands and organizations such as All Elite Wrestling and several direct-to-consumer companies. By combining mobile billboard trucks, wallscapes, experiential-style street presence and digital measurement, Callista Media Group positions itself as a flexible partner for both startups seeking a splashy launch and established advertisers wanting incremental reach. The company emphasizes attention, conversation and measurable impact as the goals of its outdoor campaigns across major United States markets.
